High Power Arduino RGB Led Blinder

This is a blinder I made with nine 3 watt LEDs. It is controlled by an arduino and is responsive to music.

Sorry for low quality, I was at a party I brought it to and only had my phone to record with. I'll post a better version when I have time.

I realize there are problems with 2 of the LEDs, it happened during transport and I just need to fix it. I'll post a new video when I get enough time to deal with it.

Sorry for the talking near the end. My friend wanted me to go somewhere, I didn't think the mc would pick me up that much

Ok, I'll have to lookup what half that means, mainly the mosfet, I JUST got a arduino board two days ago, but I'm already trying to tackle projects bigger than I know how to of course. :D Its how I learn. My first project is to replace the light bulbs in my instrument panel with RGB LED's and it'll be blue by default, and run up to red as either the tachometer, or speedometer runs up. Still a few details to decide, but I have a general idea of what I want, now.. just how to do it. :-P

@popupx Good for you! You've joined the fold my friend :) The learning curve is a bit steep but you get the hang of it eventually. Just find projects and jump in, this was actually my first big project. Also reading other peoples code and circuit diagrams helps. A mosfet is very much like a transistor, its just an electrically controlled switch basically. What kind of car are you modifying?

any details of how you did this?

@popupx Of course :) I did it pretty crudely to be honest, I plan to alter it when I have time & $ I use 9 outputs on the arduino to turn each led on or off with a power mosfet and then I have 3 outputs going to 3 power mosfets controlling R,G & B for all 9 of the leds. This uses 12 outputs and can control 9 leds with overall color control. Sound went to an analogue input and I ran it through the beat detection algorithm I wrote to do effects. Its pretty cool but very fragile, Ididnt use PCBs :\

@kctess5 I have an Old 97 Ford Explorer. Its got over 249k on it, so I'm not afraid to try stuff on it. Its also my emergency response vehicle for the fire dept, so it'll be fun to add some effects there too. :-P
